i recently removed wallpaper using dif to
expose original sheetrock that was never
painted. the wall was never primered before
the paint went on, now every coat of paint produces many paint bubbles. is lack of primer causing the paint bubbles or could it be moisture or something else? any thoughts
on this would be appreciated

Sounds like the water in the wall paint is lifting the top layer of drywall.This is due to the d/wall not being primed.Most of the time after the first coat of paint the bubbles that come up will dry out.If not using the highest grade paints,moisture from the 2nd coat will go straight to the d/wall and lift it again.These bubbles that remain after dry will have to be cut out and patched.The worst case here you would have to back up and prime with an oil primer.2nd choice to an oil would be KILZ 2 or Total One.This will stop the moisture from getting to the wall......Mike
